Specification of Letters Patent.

Application l-ed November 2, 1916. Serial No. 129,094.

To all whom t may concern:

Be it known that I, FRANCIS J. PLYM, a citizen of the United States, residing at Y Niles, in the county of Berrien and State of Michigan, have invented certain new and useful Im rovements in Interlocking Moldings for ivoted or Swinging Frames, of Which the following is a specification.

This invention relates to interlocking steel moldings peculiarly adapted for 'use in swinging or pivoted windows, commonly referred to as steel window frames.

Because of the fact that all steel sash deviates more or less from a flat surface, due to the variations in steel and inaccuracies of construction, steel moldings such as used in pivotedor hinged windows do not t iiatly against the jambs unless a very careful process of milling is carried out, which is impractical with the ordinary steel window.

, There have been several attempts to design an interlocking molding for pivoted or swinging windows to provide .a weather tight 4joint notwithstanding the variations in the steel frames. None of these, as far as I know, have ever successfully accomplished the result. It is, therefore, an object of my invention to provide interlocking steel moldings for pivoted or swinging frames so designed as to provide a weatherl tight connection when the swinging frame is in its closed position. y

The above and other objects, advantages and capabilities of my invention will become apparent from a detail description of the accompanying-drawings in which I have illustrated a device embodying one form of my invention, but the construction there shown is understood to be illustrative only.

Figure 1 is a vertical sectional view of a invention.

Fig. 2 is a similar view showing the swinging frame partially open. f

Fig. 3 is `an enlarged detail view partly in section taken from the inside of the window showing the pivoted connection.

Fig. 4 is an enlarged detail perspective view showing the pivoted connection with the stationary and swinging moldings spaced apart. j

Fig. 5 is a horizontal sectional yview taken 0n the line 5 5 of Fig. 1.

Fig. 6 is a horizontal sectional'view taken on the line 6 6 of Fig. 1, and

swinging frame embodyingone form of'my Fig. 7 is a, similar view taken on the une 7-7 of rig. 1.

Referring tothe drawings in detail, the stationary steel molding .10, which is constructed of T iron with a projecting rib 1l is secured to the frame of the opening 12 by any suitable means not shown. Pivotally connected to the stationary molding 10 near the center thereof, is a swinging molding 13 by means of the members 14 and the bolt 15, the openings in lthe members 14 being provided with inwardly extending flanges 16 to provide a suitable bearing for the bolt 15. Above the pivotal connection there is rigidly and tightly secured to the stationary molding 10 an L-shaped resilient weather strip 17, to which is secured a steel leaf spring 18 extending from the member 14 to the upper end of the molding 10, for a purpose presently to be described. A resilient weather strip 19 is rigidly and tightly secured to the swinging molding 13 by weld- Y ing or otherwise, and extends from the pivotal connection upwardly to the upper end of said molding and is designed to coperate with the weather strip 17 on the stationary molding 1() when the swinging molding is 1n closed position, as best shown in Fig. 5. lt will be noted from an examination of Fig. 5 that when the swinging molding lis in closed position and because of the configuration of the weather strips 17 and 19 and the leaf spring 18, there is a connection of live contacts, as a result of which there is provided a weather tight interlocking molding. The leaf spring 18 is so designed as to press tightly against the flange 20 on the weather strip 19 when the swinging moldingis in closedl position, `to further secure a tight connection.

Below the pivotal connection the construction of the stationary and swinging moldings is the same, except the weather strips are transposed,.as best shown in Fig. 7, this being necessary because of the fact that the swinging molding above the pivotal connection moves inwardly or in the direction indicated by the arrow in Fig. 5, while below-the pivotal connection it moves outwardly, or in the direction of the arrow indicated in Fig.

'7. Of course it will be understood that these parts could be arranged so that the upper portion of the device would swing outwardly and thelower portion swing inwardly, but as I have illustratedv them, the upper portion swings inwardly and the lower outwardly. The weather strips 17 and 19 are made of resilient material and so formed as to provide a high degree of resiliency inorder to compensate for displacement of the steel moldings with respect to each other, due to expansion, contraction, settlement of the building or other causes, and to at all times provide a weather tight joint, notwithstanding the variation in the moldings and the changes which may take place after being installed from the causes referred to. The members 14, which form a part ofthe pivotal connection, are so designed as to tightly engage each other and thus form a tight connection at the pivotal point.

It will be noted from Figs. 5 and 7 that before the air or wind could pass through the interlocking molding shown, it would be necessary to passthrough five contacts. Assuming that it did pass contacts 21, 22 and 23, the air orwind would then practically become dead, where it would form an air cushion and would be there retained by the contacts 24 and 25.

I claim:

1. In combination with a frame, a stationary molding, a molding pivoted thereto and adapted to swing vertically therein, resilient weather strips on said moldings, coperating with each other to form a dead air space when in closed position, and a leaf spring secured to one of said resilient weather strips and coperating with the` other weather strip to form a tight contact between said weather strips when in closed position. l

2. In combination with a frame, a. stationary molding, a molding pivoted thereto and adapted to swing vertically therein, a substantially L-shaped resilient weather strip secured to the upper portion of said stationary molding, a resilient weather strip secured to the upper portion of said swinging molding adapted to form three contacts with the resilient weather strip on the stationary l molding, a substantially L-shaped resilient weather strip fixed to the lower portion of low the pivoted connection, and a leaf spring A in said dead air space adapted to form a tight contact between said weather strips.

3. In combination with a frame, a' stationary molding, a molding pivoted thereto and adapted to swing vertically therein, a substantially L-shaped resilient weather strip secured to the upper portion of said stationary molding, a resilient weather strip secured to the upper portion ofisaid swinging molding adapted to form three contacts with the resilient weather strip on the vsta-- tionary molding, and one contact :with the ,stationary molding, a substantially L-shaped resilient weather strip fixed to the lower portion of said swinging molding, a resilient weather strip fixed to the lower portion of said stationary molding and adapted to form three contacts with the resilient weather strip on the swi'nging'molding, said weather strips being adapted to form a dead air space when in closed position both above and below the pivoted connection, and a leaf spring in said dead air space adapted to form a tight Contact between said weather strips.

In witness whereof, I hereunto subscribe my name to this specication in the presence of two witnesses.
